Instant Donation Receipts That Donors Love

AI sends tax-deductible acknowledgment receipts with required IRS language instantly after every donation. No delays, no missed receipts.


Why this matters

Donors need timely receipts for tax purposes, but manual acknowledgment processes delay receipt delivery and sometimes miss required IRS language. Late or missing receipts frustrate donors and can lead to lost future donations. For organizations processing hundreds of donations during campaigns, manual acknowledgment is unsustainable.


How MultiMail solves this

MultiMail's autonomous mode delivers instant donation acknowledgment receipts with all required IRS language. The AI generates personalized thank-you messages with tax-deductible receipt details. Autonomous delivery is safe because donation receipts are templated with specific required elements.

1

Receive Donation Event

When a donation is processed through your payment system, the event triggers MultiMail's AI agent with the donor's information, amount, and transaction details.

2

Generate IRS-Compliant Receipt

The AI composes an acknowledgment including the organization's name and EIN, donation amount, date, and required IRS language about goods or services received in exchange.

3

Send Immediately

In autonomous mode, the receipt is sent instantly. Donors appreciate same-day acknowledgment, and there's no risk from templated receipts to justify approval delays.

4

Track for Year-End

All receipts are logged for year-end reporting. The AI can generate annual giving summaries for donors at tax time.

Recommended oversight mode

Recommended
autonomous
Donation receipts are templated with required IRS language and dynamic donor/amount data. There is no AI-generated subjective content that could go wrong. Donors expect instant acknowledgment, and any delay reduces satisfaction and trust.

Common questions

What IRS language must be included?
For donations over $250, the IRS requires: organization name, donation amount, date, statement of whether goods/services were provided in exchange, and if so their estimated value. MultiMail's templates include all required elements automatically.
Why is autonomous mode safe for donation receipts?
Donation receipts are templated documents with dynamic data fields (name, amount, date, EIN). There is no subjective AI prose that could be incorrect. The content follows a legally required format, making autonomous delivery both safe and expected by donors.
Can I send annual giving summaries?
Yes. At year-end, the AI can compile all donations for each donor and send an annual summary with total giving, individual donation details, and IRS language. This helps donors with tax preparation.
How do I handle in-kind donations?
In-kind donations require different receipt language (the IRS prohibits the organization from assigning a value). Configure a separate template for in-kind donations that describes the donated items without stating a dollar value.
